To g/Zl'tbhom it may concern: 1 I Be it knownthat I, ABRAM HJVA'N RIPER, of Nutley, in the county of Essex and State of New Jersey, have invented anew and Improved- Fire-Extinguisher, of which the following is a full, clear, andexact description.

This-invention relates to fire-extinguishers pot the class iii-which a chemical is used in connection" with water.

, fofre been made in which the chemical is to be mixedwith water contained in'a tank and i thenejected by the pressure'created; but in simple means whereby a chemical may be suchclass of extinguishers the supply is lim-' ited to the capacity of the tank;

i The object of my inv ention'is to provide a mixed with a stream of running water, thus increasingthecapacityv of the apparatus. a I will describea fire-extinguisher embodying" my invention and then point out the novel-features inthe appendedclaims.

Reference is to be had to the accompanying drawings, forming'a'part of this specification,

in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a partial section and partial elevation of an apparatus embodying my invention Fig. 2'is a sectionon the line 2 '2 of Fig.- 1. Fig. 3 is a sectionon the line 3 3 of Fig. 1. Fig. 4 is a section on .the line 4 4; of

Fig. -1'. Fig.5 is a section on the line 5 5 of' Fig. 1', and Fig. 6 is a section on the line'6 6 ofFig.1.

Referring to myimprovement shown in Fig. 1,-.1- designates a mixing-cylinder haw ing a feed-water'hose 2 communicating. with the other end. At the inner end of thelinlet hose '2, 'or the nipple to which said" hose is f one end and a discharge-hose 3 leading. from connected, isa flap-valve 4, and forward of -"phragm '8 is attached.- The chemical-discharge pipe 6 is here shown asleading from.

i a cylinder 9, de signed to contain the chem:

ical under pressure.

Chemical -fire extinguishers have hereto- Y this diaphragm is a seriesof series of perforations arranged along its edgfj l ,a series of perforations atits center, and the} In my improvement it is who understood 'Lfind carbonic-acid gas to be a suitable material to mingle withthe water. The pipe 6 is provided witha pre sure-gage '10 and also with a regulating-Valve 5 11, designed to beclosed by gas-pressure should the pressure of the gas or chemical in the'cylinder 9 be increased toa point above the pressure of water flowing into the mixer-J.

1, thus temporarilyclosingoff the flow of; gas from the cylinder 9. p p The diaphragm 8 has a series of openings: 12v arranged around'its edge, andforwaod of partition; 13,, 14, 15, and 16. These several partitions are 65 provided with perforations, the location 0 the perforations of one partition; differin from thosecf-ancther. The objectofscrpiac ing the perforations is tocause an agitation and thorough mixture of the water and as.

7 6 'or chemical passing through the cylinder. The combined area of the several perforations. through the artitions and diaphragm willbe substantially equal to the area of-theinletand therefore the passage of the liquid notbe -retarded. The partition 13 has hr The partition 14 has its perforations arranged; radially from its center. The partition 15 has fours near its edge. v l

In the operation of myimprovementgt water from a hydrant or from any other soiirce. under pressure will enter through thepip and the gas or chemical'from the pipe 6 will; befforced into the wateigj'and as the mixed chemical and water passes through the p for'ati'ons of the several partitions the-sit I will be thoroughly mixed and will discharge in this condition through the pipe 3,;

' .It will be seen tliat the variously-perforated partitions forman agitator to thoroughlymix the flowing water and the chemical. When the Valve of the outlet 3 is closed, the pres v 5 sure of ga's'or chemical against the water i i the cylinder lwill close the flap-valve 4,'thus' preventing the: escape and loss of gasgor' chemical.

partition 16 has itssperforationsarranged in ma that the mixing of the water and gas is auto-.,,,;=-

' matic-th'a-t is, the running water and inflow ing gas will be, by the agitation employed, thoroughly mixed.

It is further to be understood that I do not limit myinvention to fire-extinguishing purposes, as it is obvious that the device maybe employed in mixing water and gas in sodafountains or similar devices.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A firc cxtinguisher, coinprisinga mixingcyliudcr, a water-inlet therefor, a perforated conical disk forward of the inlet, an outletpipe, a cylinder for containing gas, a pipe leading from said gas-containing cylinder into the mixing-cylinder and having a perforated-disk outlet discharging in the direction of the inlet of the first-named cylinder, and means for mixing the gas and water in thefirst-named cylinder, substantiallv as specified.

2. Afire-extinguishingapparatus,comprising a mixing-cylinder, a Water-inlet therefor, a water-outlet therefor, a cylinder for containing gas under pressure, a pipe leading from the gas-cylinder to the inte 'ior of the
